Abstract :
Analysis of two magnetically resonant coupled coils for wireless power transfer (WPT) is presented in this paper. This analysis is verified using sinusoidal input signal by computing voltage gain and efficiency at different alignments and frequencies. For calculation of efficiency at resonance condition, it utilizes Reflected Load Theory. It has been observed that power transfer depends on the operating frequency of the system, its orientation and existence of external and stray capacitances. An experimental test bed is developed to verify the proposed WPT system.
